Patent number: 8739358Abstract: A vacuum cleaner includes a cyclonic airflow chamber that facilitates the separation of contaminants from a suction airstream. The airflow chamber includes a chamber inlet and a chamber outlet, with the chamber inlet being fluidically connected with at least one of a suction nozzle and an above-the-floor cleaning tool. An exhaust filter housing includes a suction duct and an exhaust plenum, with the suction duct communicating with the chamber outlet. A suction source housing includes an open end communicating with the exhaust plenum and a closed end. A suction source is positioned within the suction source housing to define an annular exhaust flow passageway surrounding the suction source from the housing closed end to the housing open end. The suction source includes a suction inlet communicating with the suction duct and an exhaust outlet communicating with the housing closed end.Type: GrantFiled: March 8, 2011Date of Patent: June 3, 2014Assignee: Techtronic Floor Care Technology LimitedInventors: Paul D.

Patent number: 7146681Abstract: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters the main suction opening, passes through the cyclonic chamber, and passes to an outlet of the suction source. Particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.Type: GrantFiled: November 29, 2004Date of Patent: December 12, 2006Assignee: Royal Appliance Mfg.

A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.Type: GrantFiled: April 26, 2005Date of Patent: November 14, 2006Assignee: Royal Appliance Mfg.

Patent number: RE39473Abstract: An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing.Type: GrantFiled: January 6, 2004Date of Patent: January 23, 2007Assignee: Royal Appliance Mfg. Co.Inventors: Robert A. Salo, Charles J. Thur, Paul D. Stephens, Mark E. Cipolla, Michael F. Wright
